Graph the function. Is the domain of the graph discrete or continuous.
Problem 1 :
Solution :
Domain = Number of bags
Range = Number of marble.
The value of x must be only distinct values each values will have clear spaces between them.
More simply, only integer values are possible for number of bags. So, it is discrete.
Problem 2 :
Solution :
Input is width (in inches). It is continuous.
Problem 3 :
Solution :
Domain = Input = Number of hats.
Number of hat would be integer,
no hats (n = 0)
1 hat (n = 1)
2 hats (n = 2)
There is no 1.5 hats. So, it is discrete.
Problem 4 :
Solution :
Number of years may be decimal. For example, 1.5 years means 1 year and 6 months. So, it is continuous.
Problem 5 :
A cereal bar contains 130 calories. The number c of calories consumed is a function of the number b of bars eaten. Graph the function. Is the domain of the graph discrete or continuous?
Solution :
Input 0 1 2 3 4 |
Output 0 130 260 390 520 |
Ordered pair (0, 0) (1, 130) (2, 260) (3, 390) (4, 520) |
Plot the ordered pairs. Because you can eat part of a cereal bar, b can be any value greater than or equal to 0. Draw a line through the points. So, the domain is continuous
